However, our study showed the potential of BBR on decreasing IL-6 levels in serum, and it was previously stated that IL-6 plays a role in stress-related psychiatric disorders, proposing that increased gut permeability may lead to the translocation of gut bacteria and their metabolites into the bloodstream, which can activate an immune response and cause inflammation (neuroinflammation) and the implication of the proinflammatory cytokine IL-6 that impacts the brain, resulting in mood and behavioral changes [78,79]. This evidence concerns the gene IL6 and psychiatric disorder.
